I have been with my husband for nine years. Two kids, one by c-section, one v-bac. Started my period last Sunday and it was normal. Had sex after it finished the next Sunday with no spotting but had sex today and had a large amount of bleeding like a moderate flow. Bright red. I don't have any bladder infection or anything. Sex was not rough or unusual. I am still bleeding a few hours later but don't have a large amount of pain. Should I go in and get checked out?
